Application filed August 19, 1916. Serial No. 116,812;

I '0 all whom it may concern.-

Be it known that I, WALTER P. MURrnY, a citizen of the United States, and a resident -of the city of Chicago, in the county of (look and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the .fiollowing is aspecification.

This invention relatesto lining or insulae tion for freight cars, and particularly to car roofs of the tggpe shown in my pending application, Ser. 0. 59,938, filed November 6, 1915. Thepresentapplication contains subject-matter divided out of said application Ser. No. 59,938.

The objects of the invention are to pro-- insulation by means riveted or otherwise secured to the points between the plates. The invention further consists in providing a baseplate for supporting and, stiffening the roof along the eaves of the car, and for securing the roof to the car.

Further objects and details ofthe' invention appear in connection with the following description of the several embodiments, of the invention illustrated in the accompanywhat the invention connded claims.

In the drawings, wherein t e same reference characters designate the same parts in the several views, 1

Figure 1 is a plan view of a portion of the end of'a car embodying one form of the in? vention; I

Fig. '2 is an end elevation of the same;

Figs. 3 and 4' are longitudinal cross-sections ofthe same on the lines'3-3 and 4.-4, respectively, in Fig. 1, looking in the direction of the arrows; i

Fig. 5 is a detailperspective view of the end of a lining support;

Fig. 6' is a transvers cross-section of the roof shown m Figs. 1 to 4:1, inclusive, on the,

line 6- 6 in Fig. 1, looking in'the direction of the arrows;

riveted along t Fig. 7 is a cross-section of a riveted seam,' showing a modified form of roof sheet joint nndinsulation support;

Fig. 8 is a transverse cross-section of the roof at the caves of another modification of the invention, showing a bulb shaped seam cover and'a wooden lining under the roof sheets; i

Fig 9 is a longitudinal section on the line 9-9 1n.F1g..8, further illustrating the modifi'cation shown in Fig. 8; and

Figs. 10 and 11 are views similar to Figs. 8 and 9, respectively, of another form of supporting and attaching means for the sides and ends of the roof.

In Figs. 1 to 6 of the drawings, aroof embodying the invention is shown appliedto,

a, box car having wood side plates 11, but it may be ap lied to other forms of car body. The'end p ate 12 likewise is made of wood, and has a top board 13 bolted to its outer face for so porting the roof atjthe ends. of the car. i to the-outer face of the sideplate and their upper ends are -covered by wood fascia boards 15.

straight flaiages 18, along both sides of one sheet. The anges 18 of adj acent roof sheets are arranged in juxtaposition with a lining sup ort 19 between them and are covered'by he siding boards 14 'are secu'red- The roof is made oi heavy metalroof sheets 16 which are arranged crosswise-0f inverted U-shafied seam covers 20, which. are

eir lower edges to the flanges pf the roof sheets, thus constltutin the load carrying members of the roof. he lower' edges ofthe ining supports the roof sheets and hav oppositely disposed flanges 21 for supporting ,the roof liningi The seam covers extend from eaves to eaves, and their ends are .bent down, over the ends of the joints between the roof sheets. The seam covers are of varying height .being highest atthe middle ofthe car and ing in'height toward the eaves. I'am aware of a structure in which'the load supporting members have flanges supporting a. lining and also have roof flanges secured thereto, but such a construction requires heavy su porting members and does not answert e purposes of this invention.

decreas arr utopia:

constituting load carrying members, in combilnition with an insulating lin n comprisin; panels arranged next to sin plates on their inner sides and lining supporting members; ,ran between said panels vinside of pie and each havin an outportion riv ete between edges, said lining su porting ers' iuvin oppositely dispose, shelves trr infiedi' it rnation on opposite sides .iextending inside of said panel for secu'r the latterv mplaee.

biniition', in a plate. metal roof construction having standing. seams co'nstitutmg load carrying members, a combined stifl'e'nerand 1min support consisting of web members rivete into the standing seams of said plates to cause them to work together throughout. their length to su port said roof, sai web members having eternlly projectingflflnges spaced inside of said plates, and lining stri )3 arranged between said flanges and said plates.

5. A stiii'ened transverse seam e'onstruc tion 'for insulated, metal roofs comprising roof plates having stiffening flanges along their side edges extending from eaves to eaves, sheet metal st'ifl'eners of inverted T shape baring their webs vertically disposed between the flanges of adjacent plates and their horizontal flanges spaced below said plates for siipportin insulation, flanged seam caps over said plat:- llanges and vertically disposed webs, and rivets securing said platefianges, stiiieners and caps rigidly together throughout their length whereby the constitute a unitary transverse support for the. roof.

6. A self-supporting car roof C(lll'll'fllslflg metal roof shei-is arranged crosswise of the car and having l'llEll t1l(lH spaced above and p -i-ijeetinfg over the top edges of the car sides, longitudinal stiffening members arranged along the eaves and having portions spaced from the side oi: the car and secured totlie eaves ends of said roof: roof stiffening inen'ibers having iortions pro- .jectin inward over the car'si es and support, thereon, wherebysaid members acconii'i' odat e erossw i so inisalineinent between the eaves of the roof and the sides of the ear are sem red thereto to brace the our and hold the roof in place.
